I am wondering if there's a huge probability of bitcoin investing will become a company's focus. Like making a company that specializes investing of bitcoins
Any thoughts?

its a big big yes dude! because there some company if I am not mistaken which is Mercedez bench they adapted the concept of Bitcoin, Dell, and others, also some other merchants in the other country they accepted bitcoin as one of their mode of payment like Mcdonald taiwan, meaning if this things happened it means Bitcoin has a big impact to any form of business as well.
I see big companies starting to enter the crypto world, like the news that I saw that Samsung has accepted Bitcoin as a payment method. They know very well that opportunities are very wide open when using Bitcoin in their business.
